Fig. 9 is a greatly enlarged fragmentary sectional view, with the parts in elevation, of a container head provided with an external bead having a reentrant under surface, a molded preheated thick walled thermoplastic closure cap loosely fitted over the mouth opening of the head and encompassing the aforesaid bead, and a seal forming machine element depicted in dot and dash outline in proper position to begin a rollon sealing operation to reform the lower skirt portion of the closure cap, in a heated state, against and under the reentrant under surface of the bead; and

Fig. 10 is a greatly enlarged sectional view, in elevation, of a container head with two beads, each of substantially square cross-section, sealed with a closure cap having a skirt portion reformed in direct contact with under sides of both beads and with the intervening exterior surfaces on the container.

In Figs. 1 to 6 inclusive, reference numeral Ill designates a glass receptacle or rigid container for storing, transporting and dispensing various liquids or fluids such as, for example, liquid cosmetic preparations, polishing, or cleaning fluids, etc. The container It has an upstanding head in the form of a tubular neck 12 with rounded axially spaced external beads i3 and Hi disposed one above the other and separated by an external concaved wall surface 15. The neck I? has an upwardly open mouth passage IE through which the fluid contents flow when the container is inverted, and the outer rim of the container head I? at the upper end about the mouth opening it to the container is formed with a series of circumscribing flats to provide a hexagonal lip i8, as shown in Figs. 2, 5 and 6.

In the form shown in Figs. 1, 2, 3 and 6, the combined sealing closure and dispensing device for the container comprises inner and outer threadingly connected members 29 and 2| respectively each formed as molded generally cuplike bodies of organic thermoplastic material having relatively thick top and side walls. The organic thermoplastic materials of which the plastic members 28 and 2| may be formed may vary in nature and have different degrees of hardness and flow characteristics, so that different organic thermoplastic materials may be used to produce these relatively thick walled molded bodies having similar nature or like properties for application to the container ID in accordance with the invention. Preferably, the molded plastic members 28 and 2! are formed of cellulose acetate butyrate which is an organic thermoplastic material known in the plastic molding art under the trade name of Termite II and manufactured by the Tennessee Eastman Corporation, Kingsport, Tennessee. Molded articles formed from cellulose acetate butyrate have the following general characteristics: excellent dimensiona1 stability, high resistance to shrinkage and distortion under varying conditions of temperature and humidity, low moisture absorption, high impact strength, and improved surface finish.

The inner member 29 which constitutes the sealing closure member for the container [9 has a generally fiat top 22 with an upstanding axially disposed hollow conical projection 23 the side wall of which is formed with a fluid discharge vent or aperture 2 3 therethrough. The size of the aperture 2:!- may vary to suit the nature and viscosity of the fluid to be dispensed from the container 18.. Thus, for volatile fluids one or more very fine or minute apertures will be used whereas when viscous liquids are to be dispensed from the container an aperture of substantial size will be utilized. As illustrated, the closure member 29 is formed with an externally threaded upper portion 25 and a lower relatively thick walled depending annular skirt portion 26 delining a cylindrical open bottomed chamber extending axially inwardly from the bottom of the closure member and terminating in an annular end wall with an axially disposed feed opening. The inner wall surfaces of this chamber at the innermost end thereof adjoining the back or end wall are formed with a series of circumscribing flats to provide a twelve-sided socket 29 which will have interlocking engagement with the hexagonal lip 58 for restraining the closure member 2t from rotation about the container head I2 when the closure member is secured permanently thereto.

Fixed within the closure member 26 against the top wall of the cylindrical chamber is a sealing ring 35 of any suitable material, for example,

cork, synthetic rubber, or other resilient and compressible material the character of which will be unaffected by the fluid contents of the container.

According to this invention, and as shown in Fig. 6, the closure member 20, after being preheated to a temperature above its softening point, is placed while in a heated state over the container head with the depending skirt 25 completely embracing the beads l3 and i4 and extending for a substantial distance below the lower bead I3. When thus positioned, the hexagonal lip 18 will have interlocking connection with the twelve sided socket 29 provided interiorly of the open bottomed chamber of the closure member 20. While still in a heated state, the closure member 20 is forced downwardly by a pressure block 3| to compress the sealing ring 30, and while the closure member 20 is thus held by the pressure block 3! the skirt portion 25 is firmly forced radially inwardly against the container neck and the softened heated thermoplastic material of the skirt 26 deformed, reformed and forced into'direct contact and tight sealing relationship with the exterior concaved wall surface 55 and adjoining portions of the beads I3 and I4 bordering thereto by a suitable roll-on tool, for example, the rotatable spinning disk 33, the arrangement of which will be more fully described hereinafter, and arranged to be thrust in the direction indicated by the arrow against the outer portions of the closure skirt 2% to be reformed.

The pressure block 3| and the spinning disk 33 may form elements in a known form of bottle capping apparatus such as that disclosed in U. S. Patent No. 1,674,266 to Sharp. The substitution of the pressure block 3| here shown for the one shown in the above mentioned Sharp patent does not change the mode of operation of that apparatus when used in accordance with the present invention. As illustrated in Fig. 6, the pressure block13 I iislsuitablyeaffixed tosaiverticallyzmovable post 35'and the-pressure block :has a zdepending annular metal rrim..-portion136 which :defines a relatively shallow cup-like recess 337. "The pressure block 3| is provided witha central cylindrical bore 338 ofsuitablesize for receiving. theconical projection :23 -.of the closure .memberx20, ztheannularxrim F365 serving ;to effect centering of :the closure. inemberrzll with. respect to. the pressure blockz,3.l duringthecapping operation. *Thelower end of l the .rim "portion 736 :of the pressure'tblock preferablyeprojects .down over the top-edge portion of the ,closure member when .therecesstfi is :fullyseated upon the top of 171160105113611118111- ber, in which case, theconical projectionwfl .is housed wholly awithincthe central hole .238 of the pressure block ;-3.I

.In thecourseof the capping and roll-on operaticnszthe ;c1osure:member=.2 0 :is forced downwardly by c:the;;post and thewpressure member "31 to compress the sealingring '30 and-. hold sitwin a compressed state in tight sealing :engagement with the upper .end. opening of theucontainer headzIZ.

To carry out the spinning -or.roll-on operation, ias;rep resented .inpFig. 6, the rotary spinning disk-3:3 is there. shown asrbeing, attached-to a shaft rotatably mountedwin the outer end ofanlarm which may be suitably arranged 'for ilateral movement-towardsand from the container ahead l2 such as, for example, in the apparatus :disclosed in theaforesaidzsharp patent. Shaft 45 is yieldingly urged upwardly by a spring which bears at one end upon a nut lt attached. to the upper end of :the shafteandat its other end upona ccl-ar5il resting upon the outeriend of arm L46. The arrangement here shown :is such that the same mount for the spinning :disk can ibeuused for rolling the closure member 20 onto a :beaded container neck, as shown inFig. f6, 1012a. closure memberi20 uponqa threaded container neck 12.

While there has beenshown in *Figs. Grand '7 ;a single :spinning disk element for rolling on and reforming theclosure skirt around thecontainer neck, it is to be understood that in practice, it is preferred to use .a plurality of such disks spacedv at .equal angular intervals around the container neck and having planetary.movementthereabout. :Returning now to thespecific structure :of the combined closure and dispensing device'zshown in .ELgs. .1 .to :6 inclusive, the outer plastic member 2| thereof, as previously stated, resembles arr-inverted cup-like body of molded organic thermo plastic material having a relatively thick flat top wall :66 with sloping side portions contiguous therewith :and a depending relatively thick .13111- nular skirt portion 63 defining an inwardly :directeddeep open bottom recess .64. The inner wall @portionof. said recess 6.4 is provided with internal screw threads complementary to the threads 25 of the inner closure member for threading connection and rotatablymounting of .the outer member 12! thereto.

:In Fig; 7 the thermoplastic .closure. skirtl 6f :in a .heated state, is iaffixed'to "the container =|IB'::by being deformedradially 'by the rotatable spinning :or roll-on disksSG and the heated :material reformed :around and lockedintothe threads .on the container neck :l2',. Thus,.:in the reforming operationillustrated in Figure f imthe. spinning disk 33" is pressed radially inwardly against; the closure :skirtflfi and relative rotation eitec'ted between :the .container l0 "and: the spinning disk .33'-,.in the courseof which operation :thedisk 33" softened thermoplastic material of the closure skirt 26' into the groove of the thread '5! progressively from the upper to the lower end of the thread. This results in spinning upon the plastic closure skirt of a thread in tight conformity with.

the threads of the container to form a fluid tight primary seal thereto and which will result due to the spring-back tendency of reformed thermoplastic material of the closure skirt and the resiliency of the sealing gasket 38 when the pressure block 3! is raised to remove its pressure upon the closure member In the modification shown in Fig. 3 the glass container 80 has afiixed thereto a dispensing cap 8| formed of a molded thermoplastic material with a depending flange 82 rolled on while in a heated state by a spinning disk 33" and interlocked under an exterior lip 83 formed at the top of the container neck. The cap 81 carries an upstanding tubular boss 34 through which is inserted the shank 85 of a removable pin stopper 86. Closing the neck discharge opening of the container is a tubular stopper 8! made of a high stretch plastic, such as polyethylene, and suitably attached at its upper end as by a layer of cement 88 to the under side of the cap 8| in such relation thereto that the projecting shank 85 of the pin stopper 86 will extend into and completely close the axial passage through the stopper 8?. The

outer peripheral sides of the stopper 8? preferably P eter of the container discharge opening to make a tight push fit therein.

In Fig. 9 is shown another form of the invention wherein a molded thick-walled thermoplastic sealing cap 90 with its internal packing ring is placed, while in a heated state, over the mouth opening of the neck l2' of the glass container 10". In this instance, the intermediate portion of the container neck 12 is formed with an external bead 9| having a reentrant undersurface 92, and the cap 99, after being applied over the neck IZ' in the manner just described, has its depending skirt 93 loosely fitted about the bead 9| so as to encompass the latter while the lower portion of the skirt Q3 extends downwardly below the bottom of the bead ill for a distance substantially equal to the radial width of the underside of the bead. Thus, sufficient thermoplastic material in the portion of the skirt 93 depending below the bead 9| will be assured for reforming and being ironed, in a heated state, against and under the reentrant undersurface of the bead 9|, as indicated at 93' in dot and dash outline, by a suitable roll-on disk 33 also indicated in dot and dash outline.

Fig. 10 shows still another modification of the invention in which the glass container Hill has its head or neck l0! formed with two circular beads [02 and H13 each of substantially square crosssection and spaced apart axially of the neck I01. The mouth opening of the neck Ill! is shown sealed by the closure cap HM of organic thermoplastic material and the compressible packing ring I61. The cap N34 has a relatively thick walled depending skirt m5, here shown at the completion of the roll-on sealing operation according to this invention, with the thermoplastic material of the heated skirt 105 being reformed and ironed under and in direct contact with the undersides of the beads Hi2 and H33 and also firm- 1y against the intervening exterior finish surfaces on the. container neck HH between 'both beads.

Prior to the reforming operation the lower portion of the skirt I05 occupies the position indi cated at [06 in dot and dash outline.

It will be observed in view of the foregoing description that the novel method of the present invention can be employed for afiixing sealingv closure caps to glass containers having one or.

more rounded beads spaced apart on the container neck as shown in Figs. 1 through 6, or to a container head having screw threads as shown in Fig. '7, or to a container head having an undercut flange with a negative rake, or to a container head having one or more straight flanges as shown in Fig. 10. In each of the specific forms above described it is to be understood that a. gasket ring 30, 30, 30" or I01 of cork, rubber or.

other resilient and compressible material is provided interiorly of the sealing closure members 2i), 2!,90 and E04 respectively and isheldi'n a' compressed state for sealing the upper end opening of the container head while the heated and softened skirt portion is spun or rolled on the container neck so that the reformed thermoplastic material constituting the skirt conforms closely to and is complementary of the opposed engaged portions of the external glass finish, beads, threads or flanges to acquire a firm grip on said parts after contraction, cooling and setting of the reformed organic thermoplastic material of said closure skirt.

As a specific example of a preferred embodiment of the invention, a hollow closure having a depending annular skirt is molded as a preformed fitment of cellulose acetate butyrate having the walls of its skirt portion approximately .050 to .070" in thickness. able and reformed during the roll-on operation under an externally applied side or lateral pressure of approximately 50 lbs. while at a heat of approximately F. to F. for several sec-' onds.

During the roll-on and reforming operation, the sealing closure cap is subjected to pressure on top by the pressure block of approximately 250 lbs.

While I have described the thermoplastic thick walled dispensing and sealing closures and caps depicted in the above described forms of my in-' vention as being made of cellulose acetate butyrate, it will be understood that for certain uses where the high impact and compressive strengths afforded by the cellulose acetate butyrate is of lesser importance than tensile strength, fiexural strength and a lower percentage of elongation other plastics may be used for forming such molded fitments, such as cellulose acetate, which material because of its close resemblance to cellulose acetate butyrate in thermal, mechanical and chemical properties is virtually interchangeable therewith.
